GUIDE FOR CONVEYER-CHAINS.

SPECIFICATION forming part` of Letters Patent No. 795,166, dated July 18', 1905.

Application filed June 25, 1904. Serial No. 214,112.

To cti/Z zult/)711, it may concern:

Be it known that I, CHARLES P1Ez,a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Guides for Conveyer Chains, of

which the following is a specification.

The object of my invention is to guide a conveyer-chain around a curve without undue friction and without making' an abrupt turn.

My invention is especially useful in connection with iiight conveyer-chains used in coalstorage apparatus and is used for guiding the chain from the horizontal run to the inclined run, as described hereinafter.

The above object I'attain in the following manner, reference being' had to the accompanying drawings, in which-- Figure l is a diagram sectional view illustrating my invention. Eig. 2 is an enlarged longitudinal sectional view on the line 2 2, Fig. 3; and Fig. 3 is a transverse sectional view on the line 8 3, Fig. 2.

A is the piling-floor of acoal-storage plant.

B is the pit into which the coal is discharged from the cars which are mounted on tracks 7) A is a truss structure which extends over the piling-floor and carries the endless conveyer-chain C, which has flights c. These iiights travel over a trough a within the pit and convey coal or other material from the pit to the piling-Hoor. The structure A may be of any suitable type without departing from my invention.

Heretofore wheels have been used to guide the chain from the horizontal run in the pit to the inclined run over the piling-floor; but wheels are objectionable, as they make a too sudden turn in the conveyer, and to use a very large wheel is out of the question. I over- 40 come this difculty by mounting' an endless chain D on a frame E, having guide-rails e c at top and bottom, respectively, and sprocketwheels E at each end. Each sprocket-wheel is proper intervals on the chain D are lugs d, with which engage the projections c on the chain, so that the endless guiding-chain D is driven by the conveyer-chain C.

It will be noticed that the guide-rails e can be of any length desired and can be curved to any desired degree.

G is -the structure on which the frame E is mounted. In the present instance the frame has-angle members @2, between which extend the depending members g g of the structure G, and carried by bolts I are springs z', which 60 tend to hold the frame down so that the iiight will scrape the trough a; but in the event of the flights passing over material the springs will yield, and thus prevent the breaking of parts of the mechanism.

It will be' seen that by my invention large guide-wh eels are dispensed with and the chain can pass from the horizontal line to a line at an angle thereto on a gentle curve.

I claimas my invention- 1. The combination in an endless-chain conveyer, of a guiding-frame having curved rails at the bottom, an endless chain on said frame, guided by said curved rails and driven from the conveyer-chain,substantially as described. 75

2. The combination in an endless-chain conveyer, of a guiding-frame, having rails and an endless chain having rollers arranged to travel on said rails and to guide the conveyer-chain, substantially as described.

3. The combination in an endless-chain conveyer, of a conveyer-chain, flights thereon, a pit and an inclined path over which the chain travels, a guiding-frame situated at the point where the direction of travel of the conveyer 8"'5 changes, said guiding-frame having a curved rail at the bottom, and an endless chain on the frame guided by the rails and driven from the conveyer, substantially as described.

4. The combination of a conveyer-chain, a 90 frame, rails on said frame, a sprocket-wheel at each end of the frame, and endless chain arranged to pass around the sprocket-wheels and to travel upon the rails, and rollers carried by the chain said chain being driven by the con- 95 veyer-chain, substantially as described.
